A: Investors constantly need to remember all sorts of passwords, user names and other log on information. Making things even more complicated, investors know it's best to have a unique password for every bank and brokerage site.

But while having all these passwords might be great for security, the question is how can investors remember them all. Most up-to-date versions of Web browsers have a feature allowing them to remember passwords. Internet Explorer 11, for instance, saves passwords, if the option is selected by users, and allows them to pull these passwords into the bank and brokerage log-in screens.

Some users, though, might not feel comfortable storing their passwords on their computers or devices, especially if other people at a company or in the household share them. Many readers say they use Word or Excel's ability to password protect and encrypt data to create a documents or spreadsheets containing all their passwords. The current version of Excel, 2013, uses encryption standards that meet the standards of the National Institute of Standards and Technology, a Microsoft spokesman says. Older versions of Word and Excel, too, can be used to save documents at this level of security by following a few extra steps, which you can lookup at office.microsoft.com.
